They weren't joking at all. They want homogenious developent environvents for everyone courtesy of themeselves.
Also, they were taking bullshit about GOW production costs, seen as they had:
unlimited resource access and help from Microsoft
100% free engine and code development courtesy of their internal Unreal 3 development department.
3 years in which to develop the game
unlimited and free manufacturing, sales and marketing from their grovelling publisher (Microsoft)
